Turn your iPhone into a live magnetic-field meter. Watch the reading in microteslas (µT), follow changes in color and revisit your saved scans. Finish a basic or camera scan and save the result directly. Returning to the starting spot for a comparison is optional. Reopen the saved record without making a duplicate, compare two records, or share an image or CSV. Start measuring immediately. Set an optional starting value to follow changes in your surroundings, then use the live graph, color levels, adjustable alerts and haptics to explore the reading. IN VERSION 1.7.1 • Live magnetic-field reading and 60-second history • Adjustable change sensitivity, optional sound and haptic alerts • Starting-value and guided return comparisons • Optional Field Lens: approximate reading points over the camera view • Saved scans, two-scan comparison, image and CSV sharing • Light and dark appearance The meter works without camera access. Field Lens requires a compatible iPhone and camera permission. Camera frames and saved scan contents stay on your device unless you choose to share an export. KNOW THE LIMITS This is a magnetometer app. A changing reading does not identify a metal object, its type or depth. It cannot reliably find gold, silver or every kind of metal, and cannot establish whether drilling is safe. Magnetic cases, speakers, electronics and changes in phone position can affect readings. Camera points are approximate. Requires a magnetometer-equipped iPhone and iOS 17 or later. Free with banner ads; no subscription or account required. App interface: English, Turkish, Spanish, German, French, Brazilian Portuguese, Arabic and Japanese.

About

Smart Metal Detector & EMF

This tool uses your phone's magnetic sensor to detect nearby metal by measuring magnetic field strength. It alerts you with vibrations and sounds when metal is close, and can help locate hidden devices or electrical wires.

Highlights
  • Detects metal using magnetic sensor
  • Measures magnetic field strength (EMF)
  • Vibration and sound alerts
  • Adjustable sensitivity
  • Locates electrical wires and pipes
  • Scans for hidden devices

Metal Detector is an iOS application that detects the presence of metal nearby by measuring the magnetic field value. This useful tool uses the magnetic sensor built into your mobile device and shows the magnetic field level in μT (microtesla). The magnetic field level (EMF) in nature is about 49 μT (microtesla) or 490 mG (milligauss); 1 μT = 10 mG. If any metal is nearby, the value of the magnetic field will increase. The metal detector allows you to identify any metal object in the area because all metals generate a magnetic field whose strength can be measured with this tool. The usage is simple: launch this app on your mobile device and move it around. You will see that the magnetic field level shown on the screen is constantly fluctuating. Colorful lines represent the three dimensions and the numbers on top show the value of the magnetic field level (EMF). The chart will increase, and the device will vibrate and make sounds, announcing that the metal is close. You can change the sensitivity of vibration and sound effects in the settings. You might use the Metal Detector to find electrical wires in walls (like a stud finder), iron pipes on the ground... or pretend it's a ghost detector and scare someone! You can also use this magnetometer as a scanner to find hidden devices – cameras, microphones, or voice recorders! Metal Detector is available in the language set on your phone – now also in Russian, Spanish, and Indonesian! You can also find it in Portuguese, Turkish, and French. Now the app also has its versions in Arabic and Farsi! If you enjoy the app and want even more – you can get a pro version! Check it out in the application menu. The accuracy of the tool depends entirely on the sensor in your mobile device. Please note that due to electromagnetic waves, the magnetic sensor is affected by electronic equipment. Metal Detector cannot detect gold, silver, and coins made of copper. They are classified as non-ferrous, which has no magnetic field. But maybe you will find a metal box with some treasure inside! Try this useful tool and other apps from the Netigen Tools series! Attention! Not every model of a smartphone has a magnetic field sensor. If your device does not have one, the application will not work. Sorry for the inconvenience.
